Super Unit #506W (API 42-181-01232) is a well in Grayson County operated by Flintlock Exploration LLC, completed May 1, 2011 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued November 18, 1993, permitted to 6,949 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Flintlock Exploration LLC on the wellbore schedule.

Completion filings report one formation top, including Uv Sand.

Its 3 leases have reported 3.07M barrels of oil and 2.15M mcf of gas since January 1993, last reporting in July 2026. The leases carry 228 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 94.9K barrels injected in the 12 months reported through September 2025.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
